Interactive 3D Objects, Projections, and Touchscreens

Currently, the whole world is experiencing a pandemic outbreak of the COVID-19 virus, which is an infectious disease that is one of the types of coronavirus. Transmission of this virus can go through the surrounding goods that are touched by the hand so it is recommended to always maintain hand hygiene by washing hands with water and soap. Not at every entrance in Niti Mandala Renon field, there is a sink and no information about the location of the sink in this field, which can cause the community to be confused due to lack of information. Augmented Reality (AR) applications can be used to solve this problem because with AR can explain more interactive information because the information displayed through 3D objects is directly applied to the real world visually. In this case, AR is used to display the map of sink location information with an interactive 3D model that can be rotated and zoomed to help the community easily get the information. This application use marker-based AR with multi-target so that each map information is stored and display on the different marker. Users only need to install the application on their android device and scan the QR code provided, then the 3D map object will be displayed according to the registered marker. Based on testing this study gets a 100% success rate in functional aspects.

The paper is presents approaches to solving the problem of creating realistic interactive 3D web-collections of museum exhibits. The presentation of 3D-models of objects based on oriented polygonal structures is considered. The method of creating a virtual collection of 3D-models using interactive animation technology is described. It is also shown how a full-fledged 3D-model is constructed on the basis of individual exposure frames using photogrammetry methods. The paper assesses the computational complexity of constructing realistic 3D-models. For the creation of 3D-models in order to provide them to a wide range of users via the Internet, the so-called interactive animation technology is used. The paper presents the differences between the representations of full-fledged 3D-models and 3D-models presented in the form of interactive multiplication. The technology of creating 3D-models of objects from the funds of the State Biological Museum named K.A Timiryazev and the formation on their basis of the digital library “Scientific Heritage of Russia” of a virtual exhibition dedicated to the scientific activities of M.M. Gerasimov and his anthropological reconstructions, and vividly demonstrating the possibility of integrating information resources by means of an electronic library. The format of virtual exhibitions allows you to combine the resources of partners to provide a wide range of users with collections stored in museum, archival and library collections.

AbstractHolography is a promising technology for photo-realistic three-dimensional (3D) displays because of its ability to replay the light reflected from an object using a spatial light modulator (SLM). However, the enormous computational requirements for calculating computer-generated holograms (CGHs)—which are displayed on an SLM as a diffraction pattern—are a significant problem for practical uses (e.g., for interactive 3D displays for remote navigation systems). Here, we demonstrate an interactive 3D display system using electro-holography that can operate with a consumer’s CPU. The proposed system integrates an efficient and fast CGH computation algorithm for line-drawn 3D objects with inter-frame differencing, so that the trajectory of a line-drawn object that is handwritten on a drawing tablet can be played back interactively using only the CPU. In this system, we used an SLM with 1,920 $$\times $$ × 1,080 pixels and a pixel pitch of 8 μm × 8 μm, a drawing tablet as an interface, and an Intel Core i9–9900K 3.60 GHz CPU. Numerical and optical experiments using a dataset of handwritten inputs show that the proposed system is capable of reproducing handwritten 3D images in real time with sufficient interactivity and image quality.
